The entrance to the Outer Court was a large curtain 20 cubits (30 feet) long and 5 cubits (7.5 feet) high. It was made of fine linen, colored in blue, purple, red and white. The four-color curtain represented Christ himself. Blue points to Christ as the Heavenly One according to the Gospel of John. Purple foreshadows Christ as the Royal One testified by Matthew. Red depicts Christ as the Sacrificed One in the Gospel of Mark. White speaks of Christ as the Righteous One portrayed in the Gospel of Luke.

There was only one entrance to the Outer Court. So there is only one way to become God's children, that is, through Christ Himself. Jesus said, "I am the door; if anyone enters through Me, he will be saved." (John 10:9a)
